Patent number: 11896796Abstract: A retrograde disposable intravenous (IV) set is disclosed. The IV set includes a diverter housing between upper and lower portions of a fluid line, the diverter housing including a lower end and an upper end extending away from the lower end and the fluid line to a syringe port located in the upper end, and a diverter member within the diverter housing and configured to move within the diverter housing from a first position, at which a first opening through the diverter member forms a first fluid pathway between the upper portion and the lower portion of the fluid line, to a second position, at which the first fluid pathway is blocked and a second fluid pathway is formed between the upper portion of the fluid line and a syringe port. Retrograde infusion may occur when the diverter member is in the second position.Type: GrantFiled: April 24, 2020Date of Patent: February 13, 2024Assignee: CareFusion 303, Inc.Inventors: Robert Vasko, Stephen J. Bollish, Lawrence Farhat, Daniel Abal, Robert Dwaine Butterfield

Patent number: 11603931Abstract: A high temperature secondary seal between a rotating seal face adaptor sleeve and a rotating shaft does not consume additional axial space beyond the axial space occupied by the secondary seal. The seal includes a single ring drive collar comprising a plurality of radial directed bolts in tapped holes. As the bolts are tightened they enter a cylindrical cavity in the drive collar and impact therein a sloped surface of a crush ring. The vertical force thereby applied to the crush ring displaces the crush ring axially into a secondary graphite sealing element, thereby crushing the secondary sealing element against the adaptor sleeve and shaft, and forming a seal there between. The crush ring sloped surface can terminate in a vertical face, so that upon sufficient displacement of the crush ring the bolts abut the vertical face and impact the shaft, fixing the drive collar to the shaft.Type: GrantFiled: December 16, 2019Date of Patent: March 14, 2023Assignee: Flowserve Management CompanyInventors: Glenn Robert Owens, Jr., Jack Robert Vasko

Publication number: 20210338923Abstract: Systems and methods of micro-infusion of medical fluids are disclosed. Micro-infusion systems may include a pump, a patient interface, tubing between the pump and the interface, and a micro-infusion device along the tubing. A first portion of the tubing above the micro-infusion device is longer than a second portion of the tubing below the device. The micro-infusion device may include a chamber in-line with the tubing, a first valve between the chamber and the first portion of the tubing, a second valve between the chamber and the second portion of the tubing and a third valve between the chamber and a dump chamber. The second valve may be slidably disposed within the chamber. A medical fluid may be provided into the chamber that slides the second valve displacing another fluid in the chamber through the third valve into the dump chamber.Type: ApplicationFiled: July 19, 2021Publication date: November 4, 2021Inventors: Edward BROWKA, James FENTRESS, Lawrence FARHAT, Robert VASKO, Theodore MOSLER, David FOSHEE, George MANSOUR

Patent number: 10632299Abstract: Systems and methods are provided for intermittent microinfusion. A system may include a pump and an IV set that includes a y-port valve disposed below a pump interface portion of the IV tubing. The y-port valve may include an internal valve member that allows fluid to flow from the pump to a patient when no syringe is attached to the y-port. The internal valve member may be moved by the attachment of a syringe containing the medication to be infused to the y-port such that the fluid pathway from the pump to the patient is blocked and fluid from the syringe can be injected into the IV tubing between the y-port valve and the pump. The pump may retrograde pump the medication into the tubing via the y-port valve and then forward pump the medication to the patient when the syringe is removed from the y-port.Type: GrantFiled: December 29, 2016Date of Patent: April 28, 2020Assignee: CareFusion 303, Inc.Inventors: Robert Vasko, Stephen J.

Patent number: 10322273Abstract: A device introduced small volumes of fluid for delivery to a patient through a fluid line. The device includes a first arm adapted to receive a syringe and a second arm fluidly connected to an upstream reservoir that defines an internal volume adapted to receive a volume of fluid. The device includes a fluid obstruction mechanism configured to selectably block flow of fluid from the reservoir toward the patient, wherein the fluid obstruction mechanism transitions between a first state that permits fluid flow from the reservoir toward the patient and a second state that directs fluid flow from the syringe into the reservoir while blocking fluid flow from the reservoir toward the patient.Type: GrantFiled: August 14, 2017Date of Patent: June 18, 2019Assignee: CareFusion 303, Inc.Inventor: Robert Vasko
